Support structure for bicycle bottles and similar containers

ABSTRACT

A support structure for bicycle bottles includes a three-dimensional supporting cage frame ( 2 ) and anchoring structure ( 6, 7 ) for securing to a bicycle frame. The supporting structure ( 2 ) has a rear post ( 3 ) with two arms ( 4, 5 ) extending from its upper end, the arms being substantially symmetrical and diverging from each other. The arms ( 4, 5 ) are at least partially bent upwardly, forwardly and downwardly in order to embrace the lateral wall of a bottle (B), the lower end portions ( 8, 9 ) of the arms converge and are connected to each other to form a lower appendix ( 10 ) directed towards the post ( 3 ) that is suitable to support the bottom wall of the bottle (B). The arms ( 4, 5 ) and the post ( 3 ) are positioned over a substantially cylindrical surface whose inner diameter (D) is slightly larger than the outer diameter (Ø) of the bottle (B). The maximum span ( d ) between the inner edges of the converging lower ends ( 8, 9 ) of the arms is smaller than or equal to the half of the inner diameter (D) at a distance ( h ) from the appendix ( 10 ) that is substantially equal to the inner diameter (D). The support structure exhibits a reduced weight, an improved drag efficiency, a larger file of the bicycle bottle.

FIELD OF THE INVENTION

The present invention relates to a support structure for bicycle bottles suitable for practising sports and leisure, o for similar containers, of the type comprising a cage-like or three dimensional supporting frame, as well as anchoring means for attaching to a bicycle frame or to a similar member.

BACKGROUND OF THE INVENTION

Supports of the above mentioned type are known in the art, wherein the supporting frame is formed by a wire wound and bent in different ways, and so shaped as to house a bicycle bottle. An example of said known conventional supports is disclosed in the Italian application for utility model application No. V193U000020 filed by the same applicant.

Several drawbacks and shortcomings of said known types of supports are to be found in their excessive cost and weight, in their limited gripping action on the bottle, in their remarkable cross sectional encumbrance and in their insufficient aerodynamic efficiency.

SUMMARY OF THE INVENTION

The support structure according to the present invention aims at overcoming the above mentioned drawbacks, by providing a support structure for bicycle bottles and similar containers that features a remarkable cost-effectiveness, enhanced mechanical gripping action on the bottle, and further a reduced encumbrance and a suitably enhanced aerodynamic efficiency.

The above aim is accomplished by a support of the above outlined type which is characterized in that said supporting frame comprises a rear anchoring post with an upper end, two arms extending from the upper end and being substantially symmetrical and diverging from each other, said arms further being at least partially bent upwardly, forwardly, and downwardly so as to embrace the lateral wall of a bicycle bottle, the lower ends of said arms converging and being reciprocally joined so as to form a lower appendix directed towards said post, said appendix being suitable for supporting the bottom wall of said bicycle bottle.

Advantageously the arms and the post of said supporting frame are located over a substantially cylindrical surface having an inner diameter that is slightly larger than that of the bicycle bottle or container to be supported.

A main feature of the present invention is that the minimum distance between the inner edges of the lower converging ends of said arms is substantially equal or smaller than the half of said inner diameter at a distance from said appendix that is equal or smaller than said inner diameter. Thanks to this relationship, the supporting structure guarantees an excellent gripping action on the bicycle bottle even in heavy situations.

Advantageously, the inner diameter of the cylindrical surface is sized so as to be capable of supporting cycling bottles having a diameter that is shorter that the standard lengths, so as to reduce the encumbering width of the supporting frame and to increase its aerodynamic efficiency.

DESCRIPTION OF A PREFERRED FORM OF EMBODIMENT

With reference to the figures, a support structure for bicycle bottles and similar containers, overall indicated with the reference numeral 1, comprises a supporting frame 2 made of a relatively rigid material, suitable to house and removably hold internally thereof a bottle B schematically depicted in FIG. 19 with dotted lines.

According to the invention, the supporting frame 2 essentially comprises a back anchoring post 3 extending along a longitudinal axis L, with two supporting arms 4, 5 extending from the upper end of post 3.

Preferably, post 3 has a substantially “U” shaped section (FIG. 3) and is provided with means for anchoring to a bicycle frame or a similar member. In this particular case, said anchoring means consist of two holes 6 formed in corresponding recesses 7 for screw heads.

Arms 4, 5 are symmetrical and diverging from the longitudinal axis L, and they are bent along a curved space line first upwardly, then forwardly and eventually downwardly in order to embrace the lateral wall of bottle B.

Suitably, the lower ends 8, 9 of arms 4,5 converge and are reciprocally joined so as to form a substantially “V” or “U” shaped lower appendix 10 directed towards post 3 and adapted to support the bottom wall of bottle B.

Suitably, the post 3 and the arms 4, 5 are located along a substantially cylindrical surface having an inner diameter D that is slightly larger than diameter Ø of bottle B.

The lower ends 8, 9 of arms 4, 5 are formed so as to be capable of holding bottle B in a stable and reliable manner in every operating conditions, thereby avoiding any accidental removal thereof from the space between the inside edges of arms 4, 5.

To this end, at a predetermined distance h from appendix 10, the span d between the inside edges of lower converging edges 8, 9 of arms 4, 5 has a predetermined maximum value.

In particular, at a distance h which equals to the value D of the inner diameter of the supporting frame 2, the span d is smaller than or equal to the value of said inner diameter D.

Such a condition may be summarised as follows:

-   -   for h=D=dd=D/2

Preferably, the width of arms 4, 5 in correspondence of their curved upper areas is slightly smaller than half the length of the inner diameter, more specifically it is approximately equal to D/2.2.

The inner diameter D is sized so as to house bottles having an outer diameter Ø smaller than their standard sizes, so as to reduce the encumbering width of the supporting frame, thus remarkably reducing the transversal encumbrance and the aerodynamic drag, and optimising the aerodynamic efficiency of the bottle support. By way of example, the diameter D may range between 40 mm. and 50 mm., and may preferably be 45 mm long.

Preferably, the post 3 and the arms 4, 5 are unitarily formed and have a plate configuration with a plane cross-section so as to define a supporting frame 2 of a continuous and monolithic type, that can be obtained by moulding or injection moulding.

For example, monolithic structure 2 may be produced starting from a metal plate or from a multi-sandwich type plastic sheet.

The supporting structure 2 may be provided with one or more lightening holes 11, 12 or with slits shaped as a writing or a symbol positioned peripherally of the frame and along arms 4, 5.

In general, the supporting structure 2 may be provided with the bottle gripping means located along arms 4, 5.

In the embodiment shown in FIGS. 1 to 3, no gripping means are provided, because such function is uniquely exerted by the plastic material forming the supporting frame 2.

The embodiment shown in FIGS. 4 to 7 differs from the previous one only in that the gripping means consist of a centrally located pad 14 formed by an ellipsoidal shaped plate 15 made of a relatively rigid material that is anchored to portions 8, 9 of arms 4, 5, the pad 14 centrally supports a ball 16 resiliently held by a boss 17 made of a resiliently flexible material, rubber or plastics for example. Thus, bottle B will be resiliently clamped by the ball 16 against the elastic biasing action of boss 17.

The embodiment shown in FIGS. 8 to 11 differs from the previous one only in that the gripping means consist of a resilient pad 18 made of a boss 19 of resiliently flexible material, held by an ellipsoidally shaped connecting plate 20.

The resiliently flexible material forming the boss may be chosen among the group including gels, rubbers or plastic materials.

The embodiment shown in FIGS. 12 to 15 differs from the previous one only in that the gripping means for the bottle B consist of a pair of substantially identical supports 21, each formed by a metal or plastic shell 22 which can be inserted into corresponding seats of portions 8, 9 of arms 4, 5, each shell housing internally thereof a pad 23 made of gel, rubber or formed by a small air chamber.

The embodiment shown in FIGS. 16 to 18 differs from the previous ones essentially in that the gripping means for bottle B consist of a series of small elliptical rubber or plastic pads 24 formed on post 3 and provided with one or more transverse chevron groves 25, permitting the downward insertion of the bottle into the support frame while preventing upward easy removal thereof. The gripping means further comprise two rubber of plastic lips 26 inserted on to the upper edges of arms 4, 5 to further increase the gripping action on bottle B.

According to the foregoing description, it is clear that the support accomplishes its aims and particularly entails reduced weight, limited encumbrance reduced aerodynamic drag, and higher reliability in terms of capability to firmly hold the bottle.
